Not sure about any you could try Golden Gate Spiritualist Church in San Francisco to see if they know of anyone. It seems to have a decent reputation around the NSAC Sonny Gee the President is also pretty well known.

Maybe one day I'll be able to make a pilgrimage to one of these places. But in the meantime, things aren't so bad: I have the books, the magazines, the internet (including and most especially this Forum!).
